Problems solved by technology

[0005] However, during the use of LED floodlights, the entire lamp body is often used tilted. At this time, the liquid heat-conducting medium cannot be in contact with the shell where the LED is attached during use, so that it cannot form a cycle. effect, so that the ideal heat dissipation effect cannot be achieved

Embodiment Construction

[0027] A high-efficiency heat dissipation LED floodlight, comprising a housing 1, an LED lamp 6 is arranged in the housing 1, a radiator 2 is also arranged in the housing 1, and the LED lamp 6 is bonded to the radiator 2 , the radiator 2 is provided with an accommodation cavity 3 filled with a phase change liquid, and heat pipes 12 are arranged at both ends of the accommodation cavity 3 of the radiator 2 .

[0028] During use, after the LED lamp 6 emits light, it will generate heat. Since the LED lamp 6 is attached to the radiator 2, the heat emitted by the LED lamp 6 will be transferred to the radiator 2. At the same time, due to the heat sink 2 Wherein, a housing chamber 3 is provided, and the housing chamber 3 is filled with an oil phase-change fluid. Since the housing chamber 3 is in a vacuum state, the vaporization temperature of the internal phase-change fluid is reduced, so that the heat emitted by the LED lamp 6 is transferred to the After the phase change liquid, the ...

Abstract

The invention discloses an efficient cooling LED floodlight which comprises a shell. An LED lamp is arranged in the shell. A cooler is further arranged in the shell. The LED lamp is attached to the cooler. A containing cavity is formed in the cooler and filled with phase change liquid. Heat conduction pipes are arranged at the two ends in the containing cavity of the cooler. When the efficient heat dissipation LED floodlight is obliquely used, the phase change liquid can leave the position, wherein the LED lamp is attached, on the cooler, the LED lamp emits heat in the use process at the moment, the heat conduction pipes are arranged on the cooler and play a role in indirect heat conduction, heat of the LED lamp is transmitted into the phase change liquid through the heat conduction pipes, and therefore phase changes happen to the phase change liquid, a good cooling effect can be achieved even in the oblique use process, the overall cooling performance is improved, and long-time use of the LED lamp is ensured.

Description

technical field [0001] The invention relates to the field of lamps, more specifically, it relates to a high-efficiency heat dissipation LED floodlight. Background technique [0002] The basic structure of the LED is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver or gold wires, and then sealed with epoxy resin around to protect the interior. The role of the core wire, the last installation of the shell, so the shock resistance of the LED lamp is good. The field of application involves mobile phones, table lamps, home appliances and other daily household appliances and machinery production. [0003] During use, the LED will also generate heat. In the prior art, the LED is usually dissipated by mechanical heat transfer, but the heat transfer efficiency of the mechanical heat dissipation method is low, and the heat transfer efficiency has higher re...
